Aim of the paper is the historical-critical study of Castel Camponeschi (aka Castello di Prata), a village at about 25 km from L’Aquila city (Italy), with peculiar urban characteristics –a herringbone pattern– probably founded in the thirteenth century and characterized by important phenomena of modification and stratification. The study roots on the direct analysis of the built heritage through the architectural surveying, realized at multiple scales from the urban settlement to the masonry structures. According to the morphology of the historic center, it could be traced to the process of new settlement foundation that characterized the territory –the border between the Papal State and the Frederic’s Empire first, and then the Angevin kingdom–. The analysis of the village requires both a correlation with the natural and anthropic historical context in which it is inserted and, a specific study of masonry equipments, characterized by the re-used of stone elements from the nearby Vestino-Roman town of Peltuinum.
